I would be using this bolt (2 of them) to secure a table extension (the extension will have a table leg for support) to the main dining table in our r.v. My concern is related to the fact that these bolts will be hanging upside down underneath the table. When the bolt is slide into place, could the slide holder piece be easily knocked back by knees, releasing the table?

BEST ANSWER:The latch in question is not sturdy enough to support the extension if the table leg is knocked out and probably not necessary if the leg is in place. But to answer your question, it depends on how the latch is attached. If the slide faces away from the extension it would not be possible to release it by the knees. Even if the slide faces the sitting person, it would difficult to make it release if the latch handle is properly closed into it's slot.

I don't think it would be a problem. If you look at the picture of the item you can see that after you slide the bolt into the locked position, the knob can be pushed over 90 degrees, which makes it impossible to slide back to the unlocked position. One has to position the knob into alignment with the slide exactly before it can be slid back to unlock. Pretty unlikely that will happen accidentally by hitting it with a knee.

I bought two of these and have used for generally the same purpose. I built a large folding tabletop and used these to lock the two hinged halves into one large tabletop.

The bolts are long and have enough travel that keep them in place even if they happen to rotate out of locked position. They are also beefy and have a tight fit. Would take a hard knee knock to fully disengage.

The bolt is designed to be slid into place, then LOCKED into place by pushing it into the notch. Therefore, you'd have to hit it TWICE with your knee - once to push it back/knock it out of it's locked position, then again to slide it across. I don't know how likely this is to occur.
